How about these:
Some mentioned before, but with a twist.
1- Flick a lit cigarrette towards the opponent, with the words "Do you feel lucky, punk?" (/e punk)
2- Turns back to opponent, bends over and slaps own behind. (/e biteme)
3- Reaches into pocket with a smile, pulls out a lollypop and offers to the victim. "Would you like some candy?" (/e pervert)
4- Place hands on hips and taps foot inpatiently. " Not you again." (/e tapfoot)
5- Drops to the ground slamming fists and kicking like a tantrum.
(/e hissyfit)
6- Beg for mercy on your knees. (/e mercy)
7- Spits on the ground in front of you. (/e spit)
8- Blow warm breath on your fingernails, rub them on your clothes and look at them casually, ignoring the opponent and humming to yourself. (/e ignore)
Just a few of them, more ideas later.
